If PST is a straight line and PQ = QS = SR in the diagram,…

If PST is a straight line and PQ = QS = SR in the diagram, find y.
  • A.
    24o
  • B.
    48o
  • C.
    72o
  • D.
    84o
Correct Answer: Option A
Explanation

oo – 48o = 132o
24 + 132 + y = 180o = 156o + y = 180
y = 180o – 156o
= 24o
